Conserving Pacific Lamprey through Collaborative Efforts

Pacific Lamprey (Entosphenus tridentatus) have been an important part of the ecological community and co-evolved with aquatic species of the western rivers of the United States. Scarce information on Pacific Lamprey has hindered conservation and management efforts. To assess and conserve Pacific Lamprey, we developed a conservation initiative composed of three parts: assessment, conservation agreement,... Read More

Sustaining Freshwater Recreational Fisheries in a Changing Environment

Learning to Manage and Managing to Learn: Sustaining Freshwater Recreational Fisheries in a Changing Environment ABSTRACT: Freshwaters are being transformed by multiple environmental drivers, creating uncertainty about future conditions. One way of coping with uncertainty is to manage for resilience to unanticipated events while facilitating learning through adaptive management. We outline the application of these... Read More

Guiding Principles for Development of Effective Commercial Fishery Monitoring Programs

ABSTRACT: Monitoring of fishing activities is an essential component of successful fisheries management that can provide verifiable fishery-dependent data on fishing activities and help assess performance and success of fisheries management plans. Fishery managers and stakeholders have often struggled in developing and implementing effective monitoring programs due to lack of information, funding, and peer-to-peer learning from existing monitoring programs....

Climate Change Effects on Aquatic Ecosystems and the Challenge for Fishery Management: Pink Shrimp of the Southern Gulf of Mexico

Ecosystems that change through time impose new scientific challenges for fisheries management advice. We present a case study to illustrate our view on how to face such challenges. The Pink Shrimp fishery in the Southern Gulf of Mexico has collapsed. Annual yields were about 24,000 metric tons during the mid-1950s to early 1970s; currently, they are about 1,200... Read More

Broadening the Regulated-River Management Paradigm: A Case Study of the Forgotten Dead Zone Hindering Pallid Sturgeon Recovery

ABSTRACT: The global proliferation of dams within the last half century has prompted ecologists to understand the effects of regulated rivers on large-river fishes. Currently, much of the effort to mitigate the influence of dams on large-river fishes has been focused on downriver effects, and little attention has been given to upriver effects. Through a combination of field... Read More

Paleoclimate Shaped Bluefish Structure in the Northern Hemisphere

ABSTRACT: Bluefish (Pomatomus saltatrix), a highly migratory cosmopolitan predator, is the only extant representative of the family Pomatomidae. It has been the subject of many studies due to its commercial and recreational value, but much less research has been conducted on its global population structure. Here we investigate the population structure of this species and... Read More

Managing Expectations for Aquaponics in the Classroom: Enhancing Academic Learning and Teaching an Appreciation for Aquatic Resources

ABSTRACT: Exposing the next generation to nature can foster a stronger appreciation for aquatic resources, yet it may not always be possible to allow students to experience natural aquatic environments. Aquaponics, the combination of aquaculture with hydroponics, can be an effective tool in schools and classrooms to reunite students with plants and animals, promote systems... Read More
